It flows quickly during startup to provide immediate lubrication when the engine is most vulnerable, and maintains sufficient thickness at operating temperature to protect under heavy loads. Fresh oil maintains the precise balance of lubrication, cooling, and chemical stability that manufacturers designed the unit to handle.
These gaskets and o-rings require constant conditioning to remain flexible and impermeable. Oil suspends these contaminants, carrying them to the oil filter where they are trapped.
